Product Application
A desuperheater is designed to expand and reduce the pressure of the condensate line, separating steam and condensate. The steam is then introduced into a heat exchanger or deaerator to maximize its thermal energy, while the condensate is directed to a condensate tank for regular addition to the feedwater system. Its primary function is to lower pressure; if high-pressure steam is directly fed into a condenser, it can cause overpressure. This device can reduce pressure, prevent overpressure, and also includes a temperature-reducing device to lower temperatures.
Mechanical drain valves, such as free floating ball, lever floating ball, and inverted bucket types, utilize the principle of buoyancy for operation. They can automatically differentiate between steam and water and are commonly used in scenarios requiring continuous drainage with high flow rates, where drained water is collected and reused. The lever floating ball and inverted bucket drain valves have complex structures, while the free floating ball drain valves have a simple design and are leak-proof, typically used for pipeline drainage or equipment drainage.
Thermodynamic (disc type, pulse type) trap valves utilize aerodynamic principles to open and close the valves by the pressure drop generated from the redirection of vapor flow. They are suitable for applications with low flow rates, high differential pressure, and less stringent requirements for continuity. These valves have a simple structure, exhibit pulsating leakage, and are generally used for pipeline drainage.
